Abstract

Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A method of communication comprises generating, at a terminal device, information of a scheduling gap of the first network device, the first network device being associated with a first subscriber identity module of the terminal device and the second network device being associated with a second subscriber identity module of the terminal device; and transmitting the information of the scheduling gap to the first network device for requesting a switch from the first network device to a second network device without releasing a radio resource control connection with the first network device. Thereby, only traffic on a part of serving cells of the first network device is interrupted.

Description

CROSS REFERENCE TO RELATED APPLICATIONS This application is a National Stage of International Application No. PCT/CN2020/130518 filed Nov. 20, 2020. TECHNICAL FIELD Embodiments of the present disclosure generally relate to the field of telecommunication, and in particular, to methods, devices and computer storage media of communication during a switch among networks of multi-universal subscriber identity module (USIM). BACKGROUND Currently, a multi-USIM terminal device occupies a large market share. Two USIM cards may conform to same or different communication standards such as long term evolution (LTE), new radio (NR) or the like, and the radio frequency (RF) capability of the terminal device may be 1 transmit port (Tx)/1 receive port (Rx), 1Tx/2Rx, 2Tx/1Rx or the like. In some scenarios, a multi-USIM terminal device may establish a connection in a network A of USIM A and stay in an idle or inactive state in a network B of USIM B. Conventionally, when the terminal device needs to operate in the network B, such as perform data transmission or monitor paging occasion, the terminal device just releases the connection with the network A and switches to the network B without noticing the network A. This will bring a bad impact to performance of the network A. SUMMARY In general, embodiments of the present disclosure provide methods, devices and computer storage media for communication during a switch among networks of multi-USIM. In a first aspect, there is provided a method of communication. The method comprises: determining, at a terminal device, information of a point of time regarding a switch from a first network device to a second network device, the first network device being associated with a first subscriber identity module of the terminal device and the second network device being associated with a second subscriber identity module of the terminal device; and transmitting the information of the point of time to the first network device for requesting a release of a connection with the first network device. In a second aspect, there is provided a method of communication. The method comprises: generating, at a terminal device, information related to an expected scheduling gap of a first network device; and transmitting the information related to the expected scheduling gap to the first network device for requesting a switch from the first network device to a second network device without releasing a radio resource control connection with the first network device, the first network device being associated with a first subscriber identity module of the terminal device and the second network device being associated with a second subscriber identity module of the terminal device. In a third aspect, there is provided a method of communication. The method comprises: receiving, at a first network device and from a terminal device, information of a point of time for requesting a release of a connection with the first network device, the information of the point of time regarding a switch from the first network device to a second network device, the first network device being associated with a first subscriber identity module of the terminal device and the second network device being associated with a second subscriber identity module of the terminal device; and transmitting, to the terminal device, a message for releasing the connection with the first network device. In a fourth aspect, there is provided a method of communication. The method comprises: receiving, at a first network device and from a terminal device, information related to an expected scheduling gap of the first network device for requesting a switch from the first network device to a second network device without releasing a connection with the first network device, the first network device being associated with a first subscriber identity module of the terminal device and the second network device being associated with a second subscriber identity module of the terminal device; and transmitting, to the terminal device, a configuration of the scheduling gap based on the information related to the expected scheduling gap. In a fifth aspect, there is provided a terminal device. The terminal device comprises a processor and a memory coupled to the processor.
